Struct StateDiff 

pub struct StateDiff {
    pub accounts: BTreeMap<Address, AccountDiff>,
}

Net state changes, keyed by account.

Fields

accounts: BTreeMap<Address, AccountDiff>

Implementations

impl StateDiff

pub fn from_prestate(trace: &PrestateDiff) -> Self

Reconstructs explicit before/after values from geth’s diff-mode encoding:

• post lists only changed fields, so a missing field is unchanged;
• an account only in post was empty before (created);
• an account only in pre was deleted (self-destructed);
• a slot in pre but missing from a present post was cleared to zero;
• a slot only in post was zero before.

pub fn compose<'a>(diffs: impl IntoIterator<Item = &'a StateDiff>) -> Self

Folds per-transaction diffs, applied in order, into one net diff.

pub fn then(&self, next: &StateDiff) -> StateDiff

The net effect of self followed by next.

pub fn is_empty(&self) -> bool

pub fn summary(&self) -> Summary
